Description.......

These electromagnets have been expressly studied and realized for the control of oleodynamic valves.
They have a keeper sliding in a cylinder. The keeper movement takes place from the initial to the final position by means of the electromagnetic force, while the reverse motion is operated by a different force, normally a spring.
The assembly position is irrelevant, but the power outlet must be set in the axial sense only, otherwise, in the presence of a side load, a considerable wear of the cylinder in which the keeper slides would occur.
These appliances consist of an electrical part and a waterproof mechanical part. The electrical part is costituted by a coil encapsulated with the electric contacts for connector complying with DIN 43650.
